What is 81/91 Divided By 4/1

Solving $\frac{81}{91}\div\frac{4}{1}$

• Rewrite the Division as Multiplication by the Reciprocal:

$\frac{81}{91} \div \frac{4}{1} = \frac{81}{91} \times \frac{1}{4}$

• Multiply the Numerators: $81 \times 1 = 81$
• Multiply the Denominators: $91 \times 4 = 364$
• Form the New Fraction: $\frac{81}{91} \times \frac{4}{1} = \frac{81}{364}$
